The fonds consists of diaries, private ledger and cash book, architectural drawings, news clippings, correspondence, one seal, one measuring tape, and photographs relating to J.S. Costigan and family.

Gould's papers fall into two series. Family correspondence covers the years 1856 to 1860, when Joseph and his brother Charles were travelling in Europe, and consists of letters home from both young men, and their parents' replies. Manuscript music comprises two volumes of church anthems, with some organ music; some are original compositions by Gould and Samuel Warren. Related to this is Gould's brief manuscript account of the origin of the Mendelssohn Choir. Some family photographs are also included.

The Joseph Aspler fonds contains photographs, slides and negatives of productions of McGill Savoy Society, Red and White Revue and players' theatre.

The fonds contains the majority of the drawings and papers of Montreal architect and landscape architect John Schreiber, who was a professor in the School of Architecture at McGill from 1953 to 1987. These documents constitute a rich treasure of original design work, expressed in draughtsmanship of great virtuosity. John Schreiber’s work is an example of the contribution to Canadian architecture and landscape architecture of a generation of Europeans who, leaving that war-shattered continent in the late forties and fifties, found an appreciative and fertile ground for their talents and ambitions in Canada. The two hundred and thirty four projects represented in the Schreiber fonds span half a century of work and are documented in more than four thousand plans and drawings, hundreds of photographs and close to six linear metres of textual files.

The collection contains a photo album of classmates and Annie Hall, and three diplomas McGill MD, CM 1891, Ontario College of Physicians and Surgeons, 1891, and the Quebec College of Physicians and Surgeons 1892.

The John Howard Toynbee Falk fonds was created during Falk's time in Montreal, including papers and addresses on the themes of social work including the role of the church in social services. They document the ideas of a leader and educator in the field of social work. In this vein there is, for example, a letter written by William Lyon Mackenzie King to Falk as the Director of the McGill School of Social Workers. These records also complement other holdings of t he McGill University Archives, including the official records of the School of Social Work and the private fonds of the Montreal Council of Social Agencies. The fonds also documents Falk's family life and his work with refugees during the 1905 Russian Revolution.

The fonds consists of course materials, 1969-1996; Correspondence, 1974-1988; drafts of papers and addresses, 1964-1993; and documents on the Canadian Research Consortium on Southern Africa, 1992-1996.

Andreassen's papers fall into three series: personal materials, diaries, and professional files. Personal materials include family correspondence, 1929-ca 1932, and ca 30 cm of class notes and draft papers stemming from his student years, largely at Louisiana State. There are also files of private correspondence, some addressed to Mrs Andreassen, from the period 1975-1980. Andreassen's diaries cover the years 1936-1940, 1945-1952, 1962-1965, and 1968-1976. They record the working day and are interleaved with memoranda and correspondence, often of a personal nature. Professional files vary in nature with each stage of Andreassen's career, but correspondence and reports are consistent elements. To these may be added copies of surveys and inventories of the Louisiana Historical Records Survey, expense accounts and photographs arising from his work for UNRRA, records of archival deposits and drafts on an institutional history prepared as Archivist of CNR, and annual reports written as McGill Archivist.
